Transcribed Image Text:**Reflecting Shapes Over the Y-Axis**
In this exercise, we explore the reflection of an 'L' shaped figure over the y-axis. The initial shape is given on a grid with x and y axes marked. The task is to determine which of the four options (A, B, C, D) correctly represents the shape after reflection.
**Original Shape:**
- The 'L' shape is positioned on the grid, with the corner pointing right and downwards.
- The y-axis is the line of reflection.
**Options for the Reflected Shape:**
- **Option A:** The 'L' shape is flipped horizontally, appearing to face left and downwards.
- **Option B:** The 'L' shape does not appear correctly reflected; it extends to the left and upwards.
- **Option C:** The 'L' shape is correctly reflected over the y-axis, facing left and upwards.
- **Option D:** The 'L' shape seems misplaced as it faces right and upwards.
**Correct Answer:**
- **Option C** correctly shows the 'L' shape reflected over the y-axis. Notice how each part of the shape is an equal distance from the y-axis on the opposite side, creating a mirror image horizontally.
Understanding reflections over different axes helps in grasping fundamental concepts of symmetry and transformations in geometry.
